vices applied to crank-pin bearings or other moving parts ot' machinery, and particularly to that type of device sometimes called trav` cling oil-cups, the Vmotion impartedlto the cup servingto throw some of the lubricant into the duct orv passage Yleading to the part to be lubricated.

My present invention has for its object the described provided yWith means for very Va'c curately and conveniently adjusting the con-v trolling-valve which governs the quantity of lubricant through the delivery duct or passage, thejvalve being yieldingly connected with and adapted to rest upona seat, a lock,- ing device maintaining the valve inadj usted position on the seat. I have also made provision for retaining a sufficient quantity of the lubricant at the entrance of the delivery` duct to provide for the desired feed, thereby insuring the delivery of the measured quantity at each rotation or reciprocation of the part yto be lubricated. p i

thereservoir-top, the bosse passing through Y The boss is interiorly recessed to leave a shoulder o?, and the iuteriorlythreaded sleeve-likeextension d" of a disk# like valve-seat d is screwed upon the projecting end ofthe tube bx Within the boss e' ldown to the shoulder, so that the'valveseat projects above the cup c.

' ,A passage d2 through thel valve-seat communicates withthe tube bx, the eective vopening of said passage being controlled by a rotatable disk valve fu, resting on the valve- `seataiul connected therewith by a pin 10, extended through said valve and valve-seat by lock the said disk in adjusted position.. I have herein shown the said disk fu as pro-- vided with apertures l 2 '3 of different diameters` and arranged equidistant from the disk center to. register one at a time with the passage d2 in the valve-seat, as shown in Fig. 1, and in' order to prevent clogging of the apertures they are counterbored at the under side ,of the disk fu, as at 20, Fig. 1, leaving practically a thin .annular lip-like openin g through the disk. l ,i

A By lifting the disk e against the action of the Vspring s s'uciently to unlock the disk from the valve-seat the former'can be rotated to bring any desired opening l, 2, or 3 'into registry with the passage d2, so that the desired quantity of lubricant may pass into 'the delivery duct or tube 17X and thence to the part to be lubricated. A pointer Z4 on the valve-seat assists the operator in locating the passage di, though the locking-lug d3 wi1lproperly position the valve-disk and valve-seat.

The upright cylindrical Wall of the cup c is shown as' threaded to engage the threaded cap f and screw down tightly upon the Washer w, said cap having an internal depending annular fiangef, perforated at f2 and'surrounding the valve and valve-seat when in place.

Supposing that the lubricating device is mounted on a crank-pin bearing, for instance, and the reservoir filled with lubricant, at each downward stroke some of the' lubricant will be thrown up through the openin gs a and cX into the cup c, passing thence through the openings f2 within the ange f of the cap f and onto the valve-disk c, the narrow clearance-space between the periphery'of the disk and the said flange retarding the return of the lubricant to the cup on the upward stroke. This retardation insures the presence of a suf ficient quantity of lubricant to pass through the proper valve-opening into the passage d2 and thence to the delivery tube or duct 11X, and with the small valve-openings this retardation is necessary to insure the feed at each stroke. The lubricant passes comparatively slowly1 through the valve-opening, and -unless it is retained about the valve for an appreciable time it will return to the cup and reservoir Without properly feeding. This is especially true if the lubricating device is moving at a low speed. lVhen the feed is to be regulated, the cap f is removed and the valve-disk o is rotated to bring the desired feed-opening into registry with the passage d2 in the valve-seat.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A device of the class described, comprising a reservoir having a deliveryduc't, avalve# seat having an inlet-passage communicating With said duct, a rotatable controlling-'valve' yieldingly connected With and adapted to rest upon the seat, a locking device to maintain the valve in adjusted position on the seat, and means to intermittingly deliver a surplus of lubricant to the valve and to reta rd its return
